To all whom 2'2; may concern:

Be it known that I, MORRIS WV. PooL, citizen of the United States,and resident of the borough of Brooklyn, city of New York, in the county of Kings and State of New York. have invented certain new and useful Imp1w..ements in Type-VVriting Machines, of which the following is a specification.

My invention relates particularly to tally strip devices for typewriting machines and its general object is to provide improved devices of the class specified.

To the above and other ends my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

In carrying outmy inventionI arrange the tally= strip to extend around'the right hand end portion of the platen from the delivery roll holder toa receiving roll holder, mounted on a frame platen carrier. The be superposed on the which is secured to the bill sheet is adapted to tally strip, the writing being transferred to the latter from a carbon strip which is preferably wound up with the tally strip. The

tally strip is fed by devices which operate on the receiving roll holder to turn the same and wind the tally strip thereon, these devices being separate from the regular line spacing devices of the machine. For the purpose of insuring that the tally shall be line spaced the tally feeding devices are associated with line locking devices which are set to operate as the tally strip enters the printing field of the types. In order to unlock the line locking devices and permit the tally strip to be printed upon, it is necessary to press a key which notonly unlocks the line lock but also spaces the tally strip.

The gist of the invention lies in preventing the tally strip from being printed upon until after it has been fed or line spaced to move the previously printed item past the printing line.

In the accompanying drawings which illustrate one form of my invention,

Figure 1 is a central vertical sectional view taken fore and aft of a Monarch typewriting machine to which my inven ion is In the drawings the frame of the machine comprises a base 1, posts 2 and a top plate 3.

Key levers 4 are connected with sublevers 5 which in turn are connected by links 6 with type bars 7 adapted to strike the front face of a platen 8 mounted in a traveling platen carrier or carriage comprising end bars .9 and a connecting slide bar 10, the latter being grooved to cooperate with anti-friction balls 11 which also co-act with fixed guide rails 12. The usual spring drum by which the traveling carriage is drawn leftward is omitted from the drawings. The carriage feeding devices ma 1 be of ordinary construction comprising a toothed escapement wheel 13 with which cooperate dogs lt and 15 mounted on a pivoted dog rocker 16 which is connected by a link 17 with the central rearwardly extending arm of a universal bar frame 18 which carriesa universal bar 19 underlying the key levers. Associat-ed with the platen are the usual paper feeding devices comprising feed rolls 20 and 21 which extend along the platen but stop short of the tally strip at the right-hand end of the platen. The platen is rotatable for line spacing purposes by the usual line spacing devices comprising a ratchet wheel 22 connected to the left-hand end of the platen and operated upon by a pawl 23 ohm trolled by a lever or finger piece 24. Y

The tally roll holders may be mounted on a frame or support comprising end plates 25" and connected by a tie rod 27. Said frame may be detachably secured to the platen carriage at the r1ght-hand end thereof and for this purpose the plates 25 and 26" are provided with hubs 28 which fit over and are detaclnibly secured to the usual. paper finger rod 29 which extends lengthwise above the platen and is mounted on the end harsh. The plate 25 is provided with an extension 30 which is bifurcated at its end to fit over the. usual release rock shaft 31.

lli

having an are the roll holders removed. These roll holdtally feeding or between the plate 25 F25 and 26. {,lhe lefbhand ends of the shafts are formed with grooves 37 which are outside the plate 26 and receive latches 38 pivoted 39 to said When the latches fted the shafts may be withdrawn and ers, as shown in Fig. 1, are arranged above the platem'the roll holder 33 or delivery roll holder in rear of the other. The tally strip 4-0 is wound on the roll holder 33 and is led downward from the rear side thereof and extends around the platen and upward at the front side thereof, being wound on the receiving roll holder Associated with the roll holder 34. are line spacing devices which are arranged outside the end plate and: comprise a pinion l1 having a hub 42 which is pinned to the outer end of the shaft 36. Said pinion meshes with a pinion e3 pivoted at 4A to the end plate 25. Rigid with the pinion 4:3 is a ratchet wheel as with which cooperates a pawl A6 pivoted at 47 to the forward arm -18 of a tally feeding lever which terminates. at the front in nger piece or key 4) and is provided with hub 50 which bears on the rod 29 and is co a mined and a collar 51 fixed to sa d rod. A spring 52 maintains the pawl t6 constantly engaged with the r: "het wheel also the arm 48 is normally maintained against a stop pin 53 by a draw spring The rear arm 55 of the tally feeding lever is rigid with the hub 50 and curves downwardly and rearwardly therefrom, being bent or olf-set laterally leftward at its lower end as indicated at 56, the of"- set terminating in a downward extension 57 to which is pivoted at 58 a finger or trip 59, said trip dephnding from its pivot and which is adapted to .c'oliperate with the right-hand face of the extension 57 so that as the trip moves toward the lift it will be rigid with the extension whenever an obstruction is encountered by its lower end below the pivot. The line locking device or trip 59 on the carriage is adapted to cooperate with a line locking device on the frame of the machine. The latter device is in the present instance a normally upright member or step 61 pivoted at 62 to the usual line locking ball 63 of the Monarch machine, said bail extending lengthwise of and in front of the lower traelrway extension above the pivot 12 and being pivoted at its ends at 64: to the ends of said trackway. A spring 65 maintains the bail normally in the position shown in Figs. 1 and 2. Thepivoted stop member 61 is'adapted to cooperate with stop pins 66 and 67 on the bail, a spring 68 normally maintaining the member 61 against the stop 66, as shown in Fig. 2. i

The bail 63 cotiperates with a member 69 through a pin rearward from the bail and underlies a tail piece 71 of the member 69, which member is pivoted at 72 to the lower trackway 12. The member depends from its pivot and terminates at the lower end in a hook '73 which is adapted to swing under to the link 17. Normally the parts are in the'Fig. 2 position, the pin which underlies the tail, piece 71 maintaining the hook 73 disconnected from the finger 74. By dcpressing the bail 63 the pin 70 is lowered, permitting the member 69 to swing on its pivot 7 2, owing to the action of gravity and causing the hook 7 3 to engage with the finger 7d. At this time the operation of the key levers A will be prevented, owing to the fact that the universal bar 19 will be held against depression by the link 17 which in turn will be held from being lowered by the hook 73 acting on the finger 74. Thus not only will the type bars being swung up to the platen to print, but also the dog rocker 16 will be held from movement so that the escapement will be locked and the carriage prevented from advancing in letter space direction. The low-- ering of the bail and the consequent-locking of the parts, as described, is brought about in. the present instance'by the co-action o the trip 59 with the stop 61. As will be understood from Fig. 2, these parts are so disposed and arranged that the trip will be brought into ,contactive engagement with the stop 61 just before the carriage has advanced far enough to the left to bring the tally strip into the printing field or opposite the printing point, the printing point being designated by the reference character 7) in Fig. 2. lg. 2 the parts linelocking As shown in said F are positioned so that writing will take lace on the bill sheet 7 5 just to the left of the left-hand edge of the tally strip 40,. In the course of the next few letter space movements of the carriage the trip 59 will engage with the right-hand edge of the stop 61 and will swing said stop leftward against the spring 68 until the stop is arrested from further swinging movement about its pivot 62 by contact with the stop pin 67. As soon as the stop 61 is thus arrested further leftward movement of the carriage will c'ausethe trip" 59, acting through the stop 61, to depress the bail 63, permitting the hook 7 3 to swing rightward and look under the finger 74, as

7 0 which projects 7 be prevented from and a pl is free from the trip and 1s swung back 54: and the trip 59 will swing downward to rest-of the carriage and said stops can only shown in Fig. 4. This locking operation be unlocked to free the parts by an actuation takes place 'ust as the left-hand edge p0rtion of the tally strip enters the printing of the key 49. The depression of this key field. As a consequence, if the operator l of course advances the tally strip so that the should attempt to depress a printing key in I previously writ-ten tally is carried past the order to print on the tally type being locked could not swing to the platen to print, and furthermore, since the dog rocker 1G is locked against forward l swinging movement, the carriage in consequence is locked against leftward advance.

In order to release the line lock the 0pera tor depresses the key 49, resulting in the turning of the tally feed lever on its pivot lifting of the trip 59 so that the stop strip the actuated printing point and a fresh portion of the tally strip s brought into register with the printing line. Thus an efieetive check is provided which insures that the tally strip line spacing devices shall be actuated .l. desired intervals.

Although the carriage has been described as being arrested by the line locking stops prior to the actuation of the key 49, it will be understood that he operator need not wait to actuate the key until the carriage is arrested'and the line locked. ()n the contrary, it is preferable after the items of the bill have been written, to move the carriage leftward until it is brought opposite the place where the total is to be printed. To do this the carriage must be released from its escape nent devices and i i i be accomplished depression of the right-hand release key 71 rightward by its spring (18 to eontactive en gagenient with the stop (50. Simultaneously the pawl l6 will be moved downward and will cooperate with the engaged toot-h of the ratchet to turn the latter. This turning movement will be transmitted to the pinion t3 and from it to the pinion 41, the latter operating to turn the receiving roll 34 and wind the tally strip thereon. A stop pin. T6 on the plate is adapted to cooperate with the le\ er arm to limit the swinging movement of the tally feeding lever, the parts being arranged so that when the tally feeding lever is arrested by the pin To the tally strip will have been advanced a line space distance. W hen the operator releases the key 5E9 the tally feeding lever will be restored to normal position by the spring In order to insure an unobstructed leftward movement of the carriage at this time the trip or line locking stop 59 must, of course, be lifted out of the path of the stop 61, this being done by depressing the key 49 which operates also to-feed the tally strip. It will be observed that the keys 49 and 77 are in proximity to each other and so disposed that they may oe opthe left of the stop (51. Consequently theprinting key levers l may now be operated to print on the work sheet 75, the impressions being simultaneously transferred through a carbon or transfer sheet (not shown) to the underlying tally strip 40. \Vhen the carriage is restored toward the right the trip 59 will be brought into contact with the left-hand face of the upright stop (31 and yielding will turn on the pivot 58, as shown in Fi 5, dropping down again under the force of gravity to normal position after the stop 61 has been passed. The construction is such, it will be noted, that return movements of the carriage are not 59 and the'stop 61.

needed after the bill has been Written is to v depress the the carriage to move leftward until it is brought to position for printing the total on both the bill and the tally strip.

Various changes may be made Without departing from the spirit' of my invention. What I claim as new and desire to secure by Letters Patent, is
